    • No variations were observed using healing rates of 0.5-5 °C/min. Larger particles (30-150 μm) were compared to smaller (<30 μm) and mixed batches and were found to give equal values.

    • Interconversicm was ruled out by conducting the following experiments under dry conditions. (1) Reaction in the presence of 6 and subsequent filtration and transfer via syringe to 4 after 60% conversion of aldehyde (54% yield of 12). No decrease in 12 was observed after 4 h exposure to 4 and aldehyde conversion to 90%. (2) The reverse catalyst sequence using identical methods with filtration and transfer at 20% aldehyde conversion (13% yield of 11). No decrease in 11 was observed after 5.5 h exposure to 6 and aldehyde conversion to 50%.

    • This is the fastest reaction studied in this Article and would be most sensitive to these effects. These data, along with representative SEM pictures, are available in the Supporting Information.
